We divide 43810799 by 243
The aim is to understand the frequency of 243 in 43810799.

On to step 1:
243 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 243

Advancing to step 2:
243 can be fit into 43 0 times, resulting in a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 243

Let's proceed to step 3:
438 divided by 243 is 1 with a remainder of 195.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 243 from 438, we get 195.
Take the next digit (1) from the dividend and append it to 195, then repeat: 1951 / 243

Step 4:
243 can be fit into 1951 8 times, resulting in a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 1944 away from 1951, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 243

Let's proceed to step 5:
When dividing 70 by 243, we get 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 180.0
Deduct 0 from 70 and we're left with 70.
Include the next digit (7) from the dividend after 70, then repeat: 707 / 243

Step 6:
The number 243 fits into 707 2 times, leaving a remainder of 221.
The number 2 becomes the next digit in our result. 
Result so far: 1802.0
If we subtract 486 from 707, we get 221.
Take the next digit (9) from the dividend and append it to 221, then repeat: 2219 / 243

Going ahead to step 7:
If we divide 2219 by 243, we get 9 and a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 18029.0
If we subtract 2187 from 2219, we get 32.
Append the next digit (9) from the dividend to 32 and continue with: 329 / 243

Moving on to step 8:
If we divide 329 by 243, we get 1 and a remainder of 86.
Use 1 as the next digit of our solution. 
Result so far: 180291.0
The remainder is 86 after subtracting 243 from 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 9:
243 goes into 860 3 times with a remainder of 131.
The number 3 becomes the next digit in our result. 
Result so far: 180291.3
If we subtract 729 from 860, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 10:
1310 divided by 243 is 5 with a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 180291.35
The remainder is 95 after subtracting 1215 from 1310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 11:
The number 243 fits into 950 3 times, leaving a remainder of 221.
The next digit of our result is 3. 
Result so far: 180291.353
Subtracting 729 from 950 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Let's proceed to step 12:
The number 243 fits into 2210 9 times, leaving a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 180291.3539
The remainder is 23 after subtracting 2187 from 2210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 13:
243 can be fit into 230 0 times, resulting in a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 180291.3539
Subtracting 0 from 230 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 14:
If we divide 2300 by 243, we get 9 and a remainder of 113.
Put 9 as the next digit of the answer. 
Result so far: 180291.353909
If we take 2187 away from 2300, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 15:
The number 243 fits into 1130 4 times, leaving a remainder of 158.
Put 4 as the next digit of the answer. 
Result so far: 180291.3539094
The remainder is 158 after subtracting 972 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 16:
If we divide 1580 by 243, we get 6 and a remainder of 122.
Record the quotient 6 as the next digit in the result. 
Result so far: 180291.35390946
Subtract 1458 from 1580 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

The final outcome is 180291.35390946, with a leftover of 1.22e-07.
